Said .as jelly glasses or the screw at its lower end is connected in any suitable manner with a plunger head 35. The stem is also provided at its upper end with a knurled head 17 tofacilitate the manipulation of the stem independently of the plunger.-

The disk support 14 is tapped at its center, as shown at 14', to receive the threaded stud -36 of a pedestal 37 shown in Fig. 4. Said pedestal may be of any suitable construction or size and is adapted to be used duringthe sealing of small packages such likewise may be tapped as indicated at 37 to receive a threaded stud 38 of an auxiliary vacuum cupv 39 shown in Fig. 3. The vacuum cup, however, may be connected directly in the socket 14', if desired, without using the pedestal. ln the sealing of packages, such as jellyjglasses, shown in dotted lines at 40, having outside caps 41, the special cup 39 is used for cooperation with the lower rim of the vacuum hood 18, the vacuum cup being of a strong substantial nature and having a shoulder 39 corresponding substantially in form and size to the shoulder 15 of the standard package shown in Fig. 1.'

From the foregoing description of the mechanism, its manner of use may be briefly described as follows: With reference espeycially to Fig. 1, with the pet cock 29 closedyand with the hood fitted to the top of the shoulder 15" of 'the package 15 independi entlyof the permanent sealing means therev for, as herein shown,

the screw 1'9 will be set to lock the stem and hood as shown. The gasket 18 airtight connection between the hood and the outside of the package. The package caplEL or permanent sealing means for the package 15 will be set loosely upon the sealing gasket 15b upon the shoulder 15, the plunger head 35, however, not being under pressure upon the cap 15a.. Two. or three strokes ofthe lever 25 `will suffice to cause like, and the pedestal will afford a substantially.

serve to make contents of the package 15 and upon turning down the screw 33 the plunger head 35 will cause the cap 15"L to he iirmly seated in its place, and upon opening the pet cock 29 so as to restore the interior of the hood to atmospheric pressure, such pressure will act to permanently hold the cap 15 sealed. The plunger screw will now be lifted from the cap and the st em 17 with the hood attached thereto will be lifted so as to remove the sealed package and admit another to be sealed.

The above described operation will be understood as applying substantially to the treatment of packages with outside caps in connection with the auxiliary cup 39. In this operation the vacuum within the hood 18 serves to exhaust the air from the interiorof the cup and in other respects the action is quite similar to the action upon suoli receptacles as shown at 15.

Having thus describedour invention, We claim as new and desire to secure by Letters Patent The herein described portable domestic vacuum sealer comprising, in combination, a base adapted to rest in use upon a table or the like, a standard supported upon and above the base and including a disk at the bottom of the standard and a cross head at the top ofthe standard, there being provided space between the cross head and the disk to accommodate a package to be sealed, said cross head including a huh having a smooth vertical bore, a vacuum hood adapted to make airtight connection directly with the package aforesaid independently of the permanent sealing means therefor, means adjustable vertically through said hub to control the movements and position of the hood, a plunger acting through said vertical adjustable means and into the hood inpendently of the means for controlling the hood, an air pump supported upon and above said base, and a iexible tube connected directly between the pump cylinder and the interior of said hood, all of said mechanism constituting a self-contained machine and movable as such to any desired place for use or storage.

In testimony whereof we have signed our names to/this speciication in the presence of two subscribing` witnesses. from twenty to twentytw`o inches of vacuq um t o be indicated by the. indicator 31 throughthe action ofthe ump 20.
